Answer:
Area = length * width
112 = (2w+2)*w
112 = 2w^2 + 2w
0 =2w^2 + 2w - 112
0 = w^2 + w - 56
0 = ( w + 8 )( w - 7 )
w+8=0 results in negative measures
w-7=0 --> w = 7
width is 7
length is 16
Find 25 seconds in the table. That's between 20 and 30, right? So, find the median between 19 and 28:
19 + 28
---------- = 23.5

That is around 24 deep knee squats per 25 seconds. Now, use the same method for 65 seconds:
51 + 58
---------- = 54.5
2
That is around 55 deep knee squats per 65 seconds.
Now, explain the method using words. You might wanna use the words "average" or "mean" to describe that process above.

The expression is 50 + 0.25t.
<h3>How to compute the value?</h3>
It should be noted that from the information, the cell phone costs $50 a month plus $0.25 for each text message (t).
The expression will be:
= 50 + 0.25(t)
= 50 + 0.25t
Therefore, the expression is 50 + 0.25t.
